Abstract: | A search for the non-resonant decays B s 0 → μ + μ - μ + μ - and B 0 → μ + μ - μ + μ - is presented. The measurement is performed using the full Run 1 data set collected in proton-proton collisions by the LHCb experiment at the LHC. The data correspond to integrated luminosities of 1 and 2 fb-1 collected at centre-of-mass energies of 7 and 8 TeV, respectively. No signal is observed and upper limits on the branching fractions of the non-resonant decays at 95% confidence level are determined to be B({B}_s^0\to {μ}+{μ}-{μ}+{μ}-)<2.5× 1{0}^{-9}, B({B}^0\to {μ}+{μ}-{μ}+{μ}-)<6.9× 1{0}^{-10}.
